Woo hoo, the train is filling up fast! And who says we need to wait until 5:00 to put the Bailey's in our coffee?
to answer Angelia and any one else interested in a different size - You will be able to make this any size you want, even a king sized if desired. I cut down the number of the blocks and adjusted everything for this size. Another option: No reason you couldn't make a bigger block if you could figure out the math after we get to week 3 and you see where we are going with this. Naturally you'd need lots and lots of scraps, and you will be able to figure out how much you need for A and B when we get to that step.
And thank you, Angelia, you are most welcome. I really love these mystery rides.
